Title:
TOROIDAL CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2015/016080
Kind Code:
A1
Abstract:
A hydraulic pressing device (70) for pressing the input-side disc (2) in the axial direction comprises a first hydraulic chamber (75) and a second hydraulic chamber (76), and a first piston (73) that faces the first hydraulic chamber (75) and second piston (74) that faces the second hydraulic chamber (76). A lubrication hole (38) for supplying oil to the first hydraulic chamber (75) is formed on the input shaft (1) and an oil path (77) for supplying oil to the second hydraulic chamber (76) is formed in the second piston (74). Consequently, because a separate lubrication hole for supplying oil to the second hydraulic chamber (76) is not formed in the input shaft (shaft) (1), input shaft (1) production cost and labor can be reduced and because two lubrication holes do not exist on the input shaft (1) at a distance from each other in the axial direction, increased shaft length of the input shaft (1) can be limited.
